Analysis Of The Development Process And Characteristics Of Bulletproof Wear Fabrics

< p > bullet proof clothing is a kind of single soldier protection military used for human body torn from projectile or shrapnel. < a target= "_blank" href= "http://www.91se91.com/" > strong > dress > /strong > /a > more vest.

It is made of bulletproof layer and jacket.

Bullet proof clothing was developed on the basis of pin armour.

During the first World War, 80% of the total casualties on the battlefield were caused by debris from low speed and medium speed bombs or bombs. The experts were inspired by ancient armour and developed the first generation of bulletproof clothing at the end of the war.

In the "P" second world wars, the damage caused by shrapnel still accounts for about sixty percent. People have paid more and more attention to the development of bulletproof clothing. In the early 40s, some countries in the United States and Western Europe began to develop bulletproof steel products, such as alloy steel, aluminum alloy, alloy, ceramics and nylon, and used them in the battlefield.

In 60s, the second generation of bulletproof vests with high quality chemical fiber materials instead of high quality steel products began to appear.

After 70s, bullet proof clothing materials have made new progress.

< p > bulletproof vest can be divided into three parts: software, hardware and soft and hard composite.

The material of the bullet proof clothing is mainly high performance < a target= "_blank" href= "http://www.91se91.com/" > strong > textile < /strong > /a > fiber. These high performance fibers are much higher than the energy absorbing ability of ordinary materials, giving bullet proof clothes a bullet proof function. And because this bulletproof clothing is generally made of textile structure, it has quite softness and is called soft bulletproof clothing.

Hardware bulletproof vests are made of special steel plates, super aluminum alloys and other hard metal materials such as alumina and silicon carbide. The bulletproof vest is generally not soft.

In these materials, alloys, glass steel and ceramics are hard materials.

Alloy is made of two or more than two kinds of metal and non-metallic materials which are synthesized by certain methods.

FRP, or fiber reinforced plastics, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix.

< p > nylon and Kevlar are relatively new bulletproof materials. Nylon is the first synthetic fiber in the world.

The appearance of nylon has made the fabric look new. Its synthesis is a major breakthrough in the synthetic fiber industry, and is also an important milestone in polymer chemistry.

Kevlar, formerly known as KEVLAR, is also plated as Kevlar or Kevlar.

It is the brand name of a kind of aramid fiber material product developed by DuPont. The material is formerly called "poly (para benzyl two benzoyl two phenyl amine)".

This new material has low density, high strength, good toughness, high temperature resistance, easy processing and molding. Its strength is 5 times the same quality steel, but its density is only 1/5 of steel (Kevlar density is 1.44 grams per cubic centimeter, and steel density is 7.859 grams per cubic centimeter).

Because Kevlar products are tough, wear resistant, tough and soft, they have the special skills of being bulletproof.

Militarily, it is called the "armor guard".

At present, the bullet proof fabric developed by our country has reached the advanced level of international similar products, and it can effectively prevent the impact of all kinds of pistol shells around two meters away from P.

Compared with similar products abroad, it has the characteristics of light weight (3.5 kg), large protective area (0.23 square meters), and safe and reliable protective performance.

Moreover, all domestic materials are used, the production process is simple, the cost is low, and the benefits are high.
